Radeon RX 6950 XT vs Radeon RX 7900 XTX specs and performance

In our benchmarks, the Radeon RX 7900 XTX beats the Radeon RX 6950 XT in gaming performance.

Our database shows that the Radeon RX 6950 XT has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. Despite this, the Radeon RX 7900 XTX has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the Radeon RX 7900 XTX has significantly more memory with 24 GiB of memory compared to 16 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6950 XT has a slightly lower TDP at 335 W when compared to the Radeon RX 7900 XTX at 355 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7900 XTX is faster than the Radeon RX 6950 XT.
